ELECTRIC Si l ITGH.

' To all whom it may concern Be it known that I, MONROE Green, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Electric Switches, of which the following is a specification. r

' The switch can be utilized with advantage in many different connections, one illustrat1on of which 18 for controlling a range and at the same time a water heater, the construction being preferably such that one of these electric devices is always on while the other is ofi and vice versa.

In the drawings accompanying and forming part of the present'specification I have illustrated in detail one of the several convenient forms ofembodiment of the invention which to enable those skilled in the art to practise the same will be set forth fully in the following description. I do not restrict myself to this disclosure; I may deto part therefrom in several respects within the scope fpfthe invention defined by the claims following said description.

Referring tosaid drawings; Figure 1 is 'agtbp plan view of a switch involving my invention, the case for clearness, being omitted. Fig. 2 isa sectional plan view of said switch, the section being on the line 22 of Fig. 5. Fig. 3 is a sectional detail Fig. I} is a similar showing snap means.

view, the section bein on the line 44 of Fig. 3. Fig. 5 is an e evation' partly in section of the switch, the section being on the line'5- -5 of Fig. 1. Fig, 6 is a diagram illustrating the switch and certain circuit connections.

Like characters refer to like parts throughout the several figures.

The switch comprises two switching members, a main switching member and an auxiliary switching member. The terms in question are employed merely for convenience and not-with the intention of implying that one switchingmember is of. greater impor tance than the other. Each switching memher controls the action of an electric device.

Specification of Letters Patent.

Application filed May 5, 2915.

For example the main switching member can control the Sllpiij of current to a range, while the auxiliary switching member can .3 a like function with respect to a Wa- 4 .r, the organization being such that when one of the switching members on, the other is oil and. rent will aiways ie i electric devices. N hers may be of any s are both shown as to ry. they may have one or any desi al number of poles. In the-present case the main switching member has three poles and the auxiliary switching menib r two. The main switching member may be constructed iike the switch shown in reissued L i a Patent No. 11,395, issued December 32, 3 to G. V. Hart and to which reference may be had. This main switchingmember in the present case. therefore is snap operated by a suitable actuator such as a button or handie and through suitable means operates upon the auxiliary switching member all as will hereinafter more particularly appear. 89

Referring now to Fig. 6, the numeral 10 denotes a meter intersected by the service wires 11 an 12 and. as common in installations of this character. The three wires after leaving the meter 10 are connected 35 -with the contacts 14, and i6 opposite the contacts 17, 18 and 19, the tech; being arranged in i )perating pairs.

o series of con.-

The contacts 14: and it), 3 contacts 15 and 1S and the contacts .0 and i operate. From the contacts the conducto 1 or wires these constituting the load connected to a range.

The several contacts just described constitute a part ol the main switching meclm-i nisrn. From the outer wires 11 and 13 on the service side of the meter 10/ 1e wires 23 and extend, being connects \i'th' the contacts 25 and 26. The contz, cooperates 109 with the contact 28 while the contact 26 cooperates with the conta t 27, these cbntact:

25 to 28 inclusive constituting a part of the auxiliary switching mechanism. From the contacts 27 and 28 the service wires 29 and 30 extend and lead to water heater. As will be inferred, I can use the switch in many connections and as an illustration have mentioned a water heater and a range. In the construction shown the current supplied to the range is measured, whereas that supplied to the'wii'ier heater, is not. It. will be clear that when the cont-acts 14-, 155 n'nd .16 and 17, 18 and 19 are electrically bridged as shown in Fig. (i'cur'rent will be supplied by way-of the-.meter 10 to the range, the

water heater at-thistiinc being cut out and the main switch member being on. hen the main mvitchiri'g member is moved from onto off, the auxiliary switching member will simultaneously be moved from oil to on so as to electrically" bridge the contacts 25 and 'QS-and 26 andv 27rcspectively for supplying material such-as porcelain or fiber carries the contacts tons inclusive, being spaced or separated from the main support 31. As shown this auxiliary support or disk is fastened to blocksas'33 rigid with the sup; porting body 31.' The contacts H to 19 inclusive. are situated, in' the space between the main and auxiliary supports 31 and 32 and the commutator 3% off the main switching member is also located in this space. As shown the commutator Si is provided with switch blades or .p'ole pieces 35, the ends of which when the eommutator 34: is on enter between the branches of the cliplike contacts 14 to 19 inclusive.

The spindle is designated by 36, extending centrally through the commutator Si and being supported by the body 31 for rotation. As a means for operating the spindle 36 it may be equipped, with the insulating button 37. Associated with this spindle 36 is snap movement means of suitable kind as will hereinafter be set forth and which is adapted when the spindle 36 has been advanced a certain distance under the primary action of the button or actuator 37to cause a quick movement of the commutator 3%.to move said commutator from off to on orfrom on to ofi depending upon the position it occupied'before the spindle 86 was initially turned.

The commutator for the secondary switching member is denoted by 38, the auxiliary support 32 having a chamber or counterbore 39 to receive said commutator which is suitably operated from the main commutator "l he'auxiliary commutator 38 has 'pole pieces or switch blades -10 to coiiperate with the contacts to 28 inclusive. Said auxiliary commutator also has a suitable pins [2 from the auxiliary commutator 88,

the cap plate of the main commutator 34 having perforations .to receive the reduced ends 43 0f said pins which constitute a. convenient and simpleway of connecting the two commutators for movement t r.

Surrounding the spindle 36 is the coiled spring 45 .connected respectively with'the spindle and with the commutator 34. Rigid with the spindle 36 is the'ecc'entric or cam 46 fitted in the central opening of the catch plate 47, the projection 48 of which 006 r ates with the stationary detent or rigid p ate +19. When the spindle 36 is turned, the

spring will be tensioned and at the same time a they projection 48 will be moved out by the eccentric 46 acting upon the plate 47, the projection l8 being freed from the detent or ratchet plate 49 when the spring 45 has been tensioned sufiiciently to impart a snap move ment to the commutator 45 so as to move said commutator from-on to off or from of! to on depending upon its original position.

When the commutator has moved the requisite'distance, the projection 48 will enter a. second notch of the de'tent orratchet plate 49. v The pole pieces 35 and the pole pieces- 40 of the respective switching members or commutators '34 and 38 are insulated from each other and from the bodies or metal 2. An electric switch comprising a support, a switching member, I the support havingcontacts' cooperative with said switching member, means for moving the switchingmember-between on "and off positions, a second support, and a second and independent switching member, the second support having contacts coiiperative with thesecond switching member and also having an opening, the second switching member havin a driving connection with the; first switching member through said opening.

3; An electric switch comprising a' support, a switchingmember, the su port hav ing contacts cooperative with sai switching member, means for movin said switching member between-on and olf positions, 'a sec-l ,ond support, and a second and independent" switching member, the second support having contacts cooperative with the second lOl Ill

Ill

10 spindle for moving the first switching member between on and off positions, and means for moving the second switching member to off when the first switching member is moved to on and vice versa.

In testimony whereof I aflix my signature 15 in presence of two witnesses.
